SLEIGH-RUNNER.

Specification of Letters Patent.

Patented Mar. 1, 192'1.

Application led August 23, 1920. Serial No. 405,234.

T 0 all whom t may concern Be it known that I, .IoriANns MELBY, a citizen of the United States, residing at Backus, in the county of Cass and State of Minnesota, have invented new and useful Improvements in Sleigh-Runners, of which the following is a specification.

The object of my present invention is the provision of a strong and durable sleigh runner that is light in weight and while suficiently rigid for all purposes is possessed of suflioient resiliency to absorb shock and thereby prolong the usefulness of the runner.

To the attainment of the foregoing the invention consists in the improvement as hereinafter described and definitely claimed.

In the accompanying drawings, hereby made a part hereof Figure l is a broken side elevation of a sleigh runner constructed in accordance with my invention.

Fig. 2is a longitudinal vertical section of the Same.

Fig. 3 is a transverse section of the runner, showing the same on an enlarged scale.

Fig. 4, is a transverse section taken in the plane parallel to the plane of Fig. 3.

`the body of the runner and in the formation of the said bodyl in one piece of thin sheet steel or other appropriate sheet metal. The said body comprises a bottom wall 1, a top wall 2, a forward loop 3 through the medium of which the forward ends of the bottom wall and top wall 2 are joined, and side walls 4 which rise at right angles from the bottom wall 1 and have their upper portions arranged at opposite sides of the top wall 2. The side walls 4 are preferably shaped as shown, and in the preferred embodiment of my invention the said side walls 4 are brazed at 5 to the forward loo 3 and are brazed at 6 to the top wall 2.

n Combination with the body characterized as stated I employ at intervals in the body braces 7 of open-frame type, bolts 8 and nuts 9 to connect the said braces to the side walls 4 of the body, and bolts l() and nuts 11 to connect the said braces 7 to the bottom wall 1 and the top wall 2; the said bolts l0 being preferably of a length to extend throughout the height of the body. The lower ends of the bolts 10 are provided with heads 12, and the said heads are countersunk in the lower side of a metallic shoe 18 which I prefer to employ at the underside of the body, whereby, as will be readily understood, theV bolts l0 are utilized toserve the additional purpose of strongly connecting the shoe 13 to the body.

It will be apparent from the foregoing that my novel runner may be formed with facility and without the assistance of 'expensive machinery, and that by reason of its rigidity and strength as well as its resilient quality the runner notwithstanding its lightness is well adapted to the rough usage to which sleigh runners are ordinarily subjected.

Having described my invention, what I claim and desire to secure by Letters-Patent, is

The herein described sleigh runner body formed of a single piece of sheet metal and having a bottom wall, a top wall and side walls integral with the bottom wall and also having a loop through the medium of which ends of the bottom wall and top wall are joined; the loop and portions of the bottom and top walls being brazed to portions of the side walls.

In testimony whereof I affix my signature.

JOHANES MELBY.
